Function and Position

This module is positioned as a dedicated relative vibration monitoring unit. It mainly interfaces with the front-end eddy current sensors to receive, amplify, filter, shape, and linearly convert the original sensing signals, continuously collecting various parameters of the relative vibration of the rotating machinery shafts. The module can synchronously transmit the processed standard industrial signals to the upper-level control system, data recorder, and on-site display instrument, achieving real-time display, continuous storage, and historical operation status traceability of vibration data. The equipment is equipped with multiple levels of freely adjustable alarm thresholds and intelligent fault judgment logic, which can accurately identify various abnormal conditions such as vibration exceeding the limit, sensor breakage, line faults, and signal loss. Once the monitoring value exceeds the preset safety range, an alarm signal will be immediately output, alerting maintenance personnel to carry out hazard排查 and maintenance work. The product mainly serves scenarios such as daily condition inspection of units， early fault warning， and shaft system health management， providing all-weather vibration safety protection for rotating mechanical equipment.

Core Performance Parameters

The module has been specifically optimized for the input signal of eddy current probes， with high signal acquisition sensitivity. It can effectively filter out on-site noise， harmonics， and electromagnetic interference generated by frequency converters， high-voltage lines， and large-power motors， ensuring a pure and stable input signal. The vibration measurement range is suitable for the application requirements of mainstream large and medium-sized industrial rotating machinery， with excellent linear performance throughout the process， high repeatability measurement accuracy， and extremely low data drift during long-term continuous operation. The measurement results are real and reliable. The equipment has excellent electromagnetic compatibility performance and can adapt to industrial environments with strong electromagnetic interference. It supports 7 x 24-hour uninterrupted continuous operation and has an average fault-free working time that meets the standards of high-end industrial equipment. The signal output is a universal industrial standard analog signal， which can seamlessly connect with various mainstream industrial control devices， alarm devices， and data acquisition terminals. The working temperature and humidity range covers the conventional industrial indoor and cabinet environments， with strong temperature and humidity tolerance， and outstanding overall environmental adaptability.

General Compatible Accessories
